I know Du Sik's past... he was big on racing and one day he blocked the road for his race which led to a person not reaching the hospital on time and that person went into a coma.
first I want to say that I love KJ character... and love the possibility that he and IlRi ends up together tough…
Well this is late but why do you feel HT undervalued her and all that stuff you are talking about. He was the one who recognized her talent and also wanted her to stop taking care of his sister. I guess HT isn't good looking enough for you huh?
